A new general synthesis of γ-substituted γ-lactones and δ-substituted δ-lactones including dihydro-5-octyl-2(3H)-furanone, a natural pheromone, is described. The synthesis involves the regioselective β-scission of alkoxyl radicals generated from transannular hemiacetals as the key step.
描述了包括天然的信息素二氢-5-辛基-2(3 H)-呋喃酮在内的γ-取代的γ-内酯和δ-取代的δ-内酯的新的一般合成。合成涉及从环过半缩醛产生的烷氧基的区域选择性β-断裂作为关键步骤。
